The attorney general also alleges Mansel, of Pasadena, sold unnecessary repair services and parts, and that he misrepresented to consumers that he was licensed to perform HVAC services.

The attorney general's office is seeking an injunction to prevent Mansel from further violating state law and an order requiring that he return all money he collected from consumers for unperformed or unwarranted repairs and for any unlicensed work. Officials are also seeking civil penalties.

The suit comes after an 11 News I-Team story in May about customers who reported incomplete work by the company. The I-Team also reported that the company has an "F" rating with the Better Business Bureau.

Over the past three years, there have been 78 complaints -- 49 within the past 12 months -- and seven additional complaints are still pending. There are 21 allegations that consumers paid deposits and never heard from the company again.

The Better Business Bureau said that at the beginning of 2012, the business made a concerted effort to address and resolve old complaints, but earlier this year, it stopped responding and/or following through on promised refunds.

The I-Team's efforts to obtain comment from Mansel have gone unanswered.

A bizarre situation is unfolding in Baltimore in which people are paying rent to a landlord who claims he's helping fill the need for affordable housing, but there are serious questions about the living conditions inside, as well as who actually owns the homes.
